Description

Ceramic wine bottle preparation method and ceramic wine bottle
Technical field
The present invention is the improvement to the ceramic wine bottle preparation method, relates in particular to a kind of mouth sizes precision height, the ceramic wine bottle preparation method of outer bottleneck various shapesization.
Background technology
Ceramic wine bottle has distinct advantages, for example urges Chen Zuoyong and decorative appearance variety, not only as wine container; And a kind of especially ornamental, especially unique decorative effect of glazing formation is that glass wine bottle can not be realized; One of which thing dual-purpose function replaces glass wine bottle gradually; And become packing wine main body container, and particularly more and more to pay attention in the liquor packing at drinks, a large amount of famous brands of wine all adopt ceramic wine bottle to make container.
Ceramic wine bottle is produced, and prior art mainly adopts the injection forming mode, mainly contains three kinds: first method: bottle, bottleneck are by the moulding of same secondary mould once grouting.Yet since the injection forming work in-process to the finished product shrinking percentage up to 14%-17%, though adopt special tool to control internal diameter for whole mouthful after the bottleneck moulding, and uncontrollable to bottleneck outer wall precision; Big shrinking percentage causes mouth sizes utmost point disunity; And water ratio is actual when whole mouthful behind the injection forming can't accurately control, entirely with operator's experience, yet whole mouthful of different contraction period; Because the difference of shrinking also is a reason that causes the bottleneck low precision; And the difference that this contraction causes is free tolerance, and is uncontrollable at all.The mouth sizes poor consistency, poor with finishing bottle cap conformability, the one, cause poorly sealed seepage, the 2nd, can not satisfy of the false proof requirement of existing bottleneck to lid; Secondly, what injection forming used is gypsum mold, intensity difference; Mould is all lossy in the demoulding of moulding production each time; In the actual production, mould has only work-ing life 40-50 time, and the product of a secondary mould initial production and ultimogenitary product; Because the wearing and tearing of mould also are the another reasons that causes the bottleneck low precision.Second method: adopt bottle, bottleneck to separate injection forming, again bonding assembling once-firing.Separately make and emphasis to be controlled by bottleneck; For example make bottleneck raw slurry concentration through improving; Reduce water ratio; Reduce work in-process and shrink, and reduce bottleneck mould access times (for example bottleneck plaster mould access times be reduced to 30 times even still less), exchange high relatively bottleneck precision for to increase the mould loss.This method, though can improve the mouth sizes precision to a certain extent, owing to be the plaster mold injection forming still, its water ratio is high, contraction is big and the mould shortcoming that influences precision easy to wear still exists, and is not solved.The third method: be on the second method basis; With the bottleneck behind the injection forming; Be placed in the steel die, with the fashion of extrusion shaping once, for example disclosed pottery bottle split manufacturing of Chinese patent CN1739931 and molding bonded technology; 1. adopt distortion little to the finish portion base substrate, size is prone to the forming method under control, revised; The available filling forming method of body part or with roll forming or other forming methods; Perhaps the base substrate with the each several part of bottle adopts roll extrusion, slip casting or other forming methods to make respectively; 2. all base substrate parts of processing, with blank or/and the blank slurry, or they to bond with the mixture of sticker be an integral body.Though this method gypsum mould grouting moulding separately; Can improve the mouth sizes precision, but, get into the moulding bottleneck of punching block because basic base still is an injection forming; Water ratio is still about 30% (shrinking percentage 10%-12%); Deposit the bigger contraction of right existence after the extruding integer, gained bottle mouth sizes still has ± the 0.5mm tolerance, still is difficult to satisfy the requirement that the bottleneck precision improves constantly.Besides, above-mentioned three kinds of forming methods, all (for example the too early formed body water ratio of demoulding HS is low, is difficult to typing owing to receiving gypsum mold demoulding reason; The demoulding is slow excessively, and then can be because of moulded pottery not yet put in a kiln to bake moisture content volatilization, base substrate shrinks and causes the molding blank cracking), so be difficult to make special formed bottleneck, bottleneck such as perfect thread mouth, the asymmetric abnormal shape of outer wall for example.
Pottery bottle method is produced in the disclosed roll forming of Chinese patent CN1305887, difference roll forming body and bottleneck on roller press.Roll forming one be the moulded pottery not yet put in a kiln to bake shrinking percentage still about 10%, bigger shrinking percentage still causes the bottleneck precision to be difficult to control and unified; Secondly, roll forming bottleneck periphery moulding limitation can only be made the circular configuration bottleneck, can't produce special formed bottle article, for example perfect thread bottleneck.
The disclosed pottery bottle of Chinese patent CN1636690 is the bottleneck manufacture craft accurately; Adopt split roll forming pottery bottle base body and neck portion; Use the cutter repaired biscuit of accurate dimension again,, accurately control the bottleneck coordinating size through accurate control tool dimension, shape and Tool in Cutting position; With blank or/and blank slurry, or they to bond with the mixture of sticker be an integral body.Yet the shortcoming that above-mentioned water ratio is high still exists, and still is difficult to guarantee accurate consistence, still is difficult to satisfy the requirement that the bottleneck precision improves constantly; And the artificial accurately repaired biscuit of cutter, time-consuming taking a lot of work increased cost of manufacture; Besides, the limitation of bottleneck moulding is still unresolved.
Therefore ceramic wine bottle exists the mouth sizes precision low; Consistence is poor; Finishing such as bottleneck and plastics, metal, anti-fake bottle lid fitness are poor; And shortcoming such as bottleneck outer wall moulding limitation (for example can not production standard screw thread and special formed bottleneck) and forming mould loss be big, become the technical barrier that is difficult to go beyond in the ceramic wine bottle production.Because the defective bottle that causes of bottleneck is scrapped, and accounts for 2% of bottle wine output at least, wastes huge.And the ceramic wine bottle of prior art for preparing, bottleneck pug formula and bottleneck pug formula are identical.
Though at ceramic field, it is little that the hot pressing filling forming method has the products obtained therefrom shrinking percentage, can improve formed precision, and the preparation special-shaped product.But owing to receive traditional bottle manufacture craft thought Shu Bo; Though people know the hot pressing slip-casting shaping process is arranged, reality is not applied for a long time, to improving the bottleneck precision; Still just pursue simply from former technology and seek terms of settlement, also can understand by above-mentioned documents.And ceramic wine bottle burns till, all unique employing single firing process.So the not high problem of above-mentioned bottleneck precision is not resolved for a long time.
The false proof new trend of bottle; Be destruction through bottle cap; And can not add new lid again in addition and realize that a kind of method makes bottle cap be made up of inner cap and enclosing cover, inner cap fastens the back and is indissociable wringing fit with bottleneck; It then is the destructiveness disconnection of outer lid and inner cap that bottle is opened, and can't reuse and duplicate thereby reach bottle.Therefore requiring has accurate the cooperation between bottle and inner cap.Ceramic wine bottle bottleneck precision, particularly the collar extension dimensional precision is low, cause with accuracy requirement high mould firmly, the metal cap quality of fit is poor, be difficult to satisfy reach false proof requirement, so become the false proof a great problem of high-grade liquor through bottle cap.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, provides a kind of mouth sizes precision high, high conformity, and yield rate is high, can mate with the finishing bottle cap, and the bottleneck various shapesization, the ceramic wine bottle preparation method that the consume of bottleneck mould is few.
Another object of the present invention is to provide a kind of ceramic wine bottle of method for preparing.
The present invention's first purpose realizes, and is main through changing traditional ceramics Bottle neck for wine bottle forming method and process for calcining, by gypsum mould grouting moulding or slice roll forming; Change punching block hot pressing paraffin injection forming into; Improve formed precision and can obtain special-shaped bottleneck, and after adopting moulding bottleneck sintering, again with sintering or the sintering bottle with sticker bonding assembling back sintering; Thereby it is big to efficiently solve prior art pottery bottleneck molding shrinkage; Size is difficult to the accurately deficiency of control, and the deficiency that is difficult to obtain special-shaped bottleneck, realizes the object of the invention.Specifically, ceramic wine bottle preparation method of the present invention comprises and separately makes ceramic bottleneck and bottle; Both through the bonding combination, are burnt till integral body, it is characterized in that said bottleneck is shaped to punching block hot pressing paraffin injection forming; Behind the moulding bottleneck sintering, again with sintering or the sintering bottle sintering again that bonds not.
Among the present invention
Bottleneck punching block hot pressing paraffin injection forming, this innovates greatly for the present invention one, first the bottle mouth is adopted punching block hot pressing paraffin injection forming; Forming method is analogous to the slip casting of ceramics injection paraffin basically, with respect to existing gypsum mould grouting moulding and roll forming, is solid feed because of hot pressing slip casting provides mobile paraffin; Weigh easily, proportioning accuracy is high, thereby shrinking percentage is easy to control; Thereby lay a good foundation for improving precision; Greatly reduce the moulding post-shrinkage ratio, hot pressing injection forming shrinking percentage is merely 3-5%, so moulding can obtain degree of precision.And the obtained by molding work in-process, intensity is high, can prepare special-shaped bottleneck.
Behind the moulding bottleneck sintering again with bottle bonding after sintering again; This is the another big innovation of the present invention; Both can prevent that it was at subsequent production (for example bottleneck assembling, combination bottle firing deformation, cracking; And the two sintering does not match) damage of bottleneck and bottle, reduced because of bottleneck defectively again, and cause whole bottle to scrap.Above-mentioned two factor actings in conjunction have improved the bottleneck precision, have reduced factors such as the bottleneck precision is defective and have caused the bottle condemnation factor.
Sintering after the bottleneck moulding, prior art paraffin injection forming sintering method roughly the same, for example first low temperature de-waxing, back high temperature sintering; Also can adopt de-waxing and sintering once to accomplish.
The bonding of sintering bottleneck and bottle; Can adopt prior art ceramic bonding method (for example sticker bonds, bonds with material mud); The present invention is a kind of better for adopting the sticker bonding (promptly making sticker without the bottle pug) of non-mud; Non-mud sticker bonds, and more helps coordinating the contraction coupling of sintering process bottle and bottleneck, improves and burns till yield rate.The present invention better does, the fusing point of used sticker is lower than bottle pug sintered temperature, for example low 10-20 ℃ or lower, and make sticker when sintering, have melt fluidity preferably, more help the strength of joint and the connection section adaptation of bottleneck and bottle behind the sintering.
The bottle moulding both can be adopted the gypsum mould grouting moulding, also can adopt roll forming, can also adopt the hot pressing injection forming of bottleneck of the present invention.Be ceramic wine bottle of the present invention, bottle and forming method do not have special cognation.
Pottery bottleneck batching both can adopt identically with ceramic bottle, also can prepare burden different with bottle.A kind of being preferably of the present invention adopted bottleneck batching sintering temperature, is higher than bottle batching sintering temperature (for example sintering temperature is higher than 5-20 ℃ of bottle sintering temperature), the i.e. non-same material of bottleneck and bottle.Can improve the compatibility that bottleneck batching and bottle are prepared burden so greatly, carry out, make it to adapt to different bottle raw material sintering temperatures variations between different batches, guarantee to make up the high success ratio of back sintering thereby can the making of bottleneck batching be separated with the making of bottle batching.
Ceramic wine bottle preparation method of the present invention with respect to prior art, has broken the traditional ceramics bottle mode of production, expects adopting punching block hot pressing paraffin injection forming bottleneck first, and with behind the bottleneck sintering again with the novel process of bottle bonding combined sintering.Produce control easily; Broken through ceramic wine bottle bottleneck low precision (mould and high moisture content); And the insoluble technical barrier of bottleneck moulding limitation (be difficult to the demoulding, the raw material shrinking percentage is big), having realized ceramic wine bottle as glass wine bottle, mouth sizes is accurate; Variation in moulding is various, for example can do standard perfect thread and fine thread.Punching block hot pressing paraffin injection forming has not only greatly improved the bottleneck formed precision, outer bore size degree of the unification height of bottleneck; Inside and outside footpath over/under tolerance can accomplish≤0.1mm that yield rate can improve 3% at least than prior art, and greatly reduces the mould loss; Economic benefit is fairly obvious; And can satisfy liquor market fully, to bottle seal, unlatching, high request such as false proof, widened the supporting use range of novel anti-fake bottle lid; And can obtain for example special-shaped bottleneck such as perfect thread, fine thread (for example on-circular face bottleneck), make it can be used for ceramic wine bottle fully.Started ceramic wine bottle bottleneck employing punching block hot pressing paraffin slip-casting shaping process at least, and the sintering process beginning.The inventive method owing to be different from prior art, thereby distinctly prepares different vestiges in the prior art ceramic wine bottle, and for example bottleneck has the hot-injection molding pastry mouth; Mouth sizes high unity, over/under tolerance can accomplish≤0.1mm that the smooth corner angle of bottleneck are clearly demarcated, moulding abundant, can make standard thread and loaded down with trivial details moulding; After destroying bottle, there is translucent traces of adhesives bottleneck and bottle bonding part; Bottleneck raw material and bottle raw material are incomplete same; Both color and lusters are all inequality before and after the sintering (gets rid of and decorates glaze; The slip casting formed product or to burn till the back color and luster consistent) wait one or several above-mentioned distinguishing characteristicss, can be used as the difference of differentiating the inventive method shooting bottle and additive method making bottle.
Below in conjunction with two specific embodiments, the present invention is further understood in exemplary illustration and help, but the embodiment detail only is for the present invention is described; Do not represent the present invention to conceive whole technical schemes down; Therefore should not be construed as the technical scheme qualification total to the present invention, some are In the view of the technician, and the unsubstantiality that does not depart from the present invention's design increases and/or change; For example simple the change or replacement of technical characterictic to have same or similar technique effect all belongs to protection domain of the present invention.
